Granted: 1991-05-21
Abstract: ABSTRACT             A phase locked loop for synchronizing a local digital signal with an incoming data signal is described.  Parallel phase and frequency detectors compare the local and incoming signals and generate control pulse signals for controlling the frequency of a voltage controlled oscillator which generates the local digital signal.  Logic circuitry is included in both the phase and frequency detectors for adjusting the generated control pulse signals in the event of detection of elongated pulse widths of the incoming data signal, indicating one of either an absence of incoming data signal or a bipolar violation in the event the data signals are ASI encoded.  The phase locked loop is characterized by quick pull-in time, large pull-in frequency range, accurate clocking and low cost.

Patent CA-1294746-C (CA)
Inventor: RODMAN CLARKE A
IPC: B29B11/16

Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE A fiber reinforced, composite article is manufactured by forming a nonwoven, air-laid batt from a single fiber type or a mixture of fibers.  The batt is either resinated with a thermoplastic material or includes a thermoplastic binder fiber.  The batt is formed into a preform having the desired shape in a through-air mold and heated sufficiently to set the thermoplastic material, so that the resulting preform retains the desired shape and is sufficiently stiff to withstand the pressure of the injected resin.  The preform is then transferred to a resin injection mold, where the interstices between the fibers are saturated with an appropriate resin matrix.  As the fibers of the preform are saturated (or after a saturation but before the resin sets) the resin transfer mold is compressed, thereby forming the preform into its final desired thickness and increasing the concentration of the fibers to give the preform appropriate strength.  Accordingly, the preform retains the open characteristics permitting easy injection of the resin, while later being compressed to increase the concentration of the reinforcing fibers to give the resulting composite the appropriate strength.

Abstract: ABSTRACT OF THE DISCLOSURE   In a vehicle having an internal combustion engine, it is usual to monitor the oil pressure of the engine's lubrication system to prevent damage to the engine in the event the oil pressure decreases to an unacceptable level. In this regard, a gauge or a warning light on the vehicle dashboard indicates when the oil pressure is low in response to a signal from an oil pressure transducer connected to the engine lubrication system. Herein is described an improved oil pressure transducer with a relatively easily crushable thin metal base housing member. The base housing portion is generally hollow andincludes a threaded male support portion adapted to be received in a threaded aperture of the engine and fluidly communicated with the lubrication system. The base includes a molded wrenching portion of elastomeric material formed about the housing for contact by an installation tool. The molded wrenching portion is shaped on its outer circum-ference so as to facilitate rotation of the transducer by tool means without damage to the thin metal wall thereof.
